Can you get a girl pregnant if you cum inside her a little bit while she is on her period or if it is is a couple days after her period?

It's always Yes: The simple answer, "yes." there's a joke about what do you call a couple who practices rhythm method of birth control? The answer is, "parents." pregnancy is less likely to result from intercourse at these times but there's always at least some possibility. In-home pregnancy tests can tell as early as 2 weeks after conception, though if negative, must re-ck after 1st missed period. Ck w/ your md.
